question about hostname and domain

[Ovidiu]

when setting up I was asked for those details:

I gave:

hostname: hxxxx
domain: serverkompetenz.net

hxxxx.serverkompetenz.net was the pc-name I was given from the serverprovider. seemed logical to me but now when there is an error ex. I type in a url with https that doesn not have it activated and get thefolowing Bad Request error:

Bad Request
Your browser sent a request that this server could not understand.

Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.

    Hint: https://serverkompetenz.net:81/

which is not ok as there should be a link to hxxxx.serverkompetenz.net and not only serverkompetenz.net which is alink to my provider...


any ideas how I can change that? Or can I simply enter my ip for host and domain insteadf of this data?
